      abstract = {While meta-analysis is typically used to identify value  estimates for benefit transfer, applications also provide  insights into the potential influence of design, study and  methodological factors on results of non-market valuation  experiments. In this paper, a metaanalysis of sixteen  separate choice modelling studies in Australia with 130  individual value estimates relating to river health are  reported. The studies involved different measures and  scales of river health, so consistency was generated by  transforming implicit prices from each
study into a common  standard of WTP per kilometer of river in good health.  Tobit models have been used to identify the relationships  between the dependent variable (WTP/km) and a number of  variables.
The results demonstrate that values are  sensitive to marginal effects, with lower WTP/km for larger  catchments, and higher WTP/km when river health is in  decline. Values are also lower when river health has been  defined by a subset of benefit types, such as recreation  uses, vegetation health, fish health or bird populations.  While there is evidence that the framing of the choice sets  and descriptions of attributes have systematic impacts on  values, there is very
little evidence that choice  dimensions, collection methods, sample sizes, response  rates, statistical methods or publication status have  influenced value estimates. Tests of apparent author  effects show that these become insignificant when other  explanatory variables are
included in the models.},
